Battery Maintenance
DANGER
Use all safety precautions specified by the battery manufacturer when working with the battery.
Flammable, explosive gas. (produces hydrogen gas while charging or during operation). Keep area around battery well ventilated and keep from any fire source.
Battery electrolyte contains corrosive, toxic chemical. (dilute sulfuric acid). Avoid contact with eyes and skin.
Shock or Fire due to electric short- circuit. Disconnect battery cables before inspecting electrical system and never "spark" battery terminals to test for charge.
Mishandling of the battery shortens the service life of the battery and adds to maintenance cost. When handling the battery do the following:
Be careful not to let the battery electrolyte come in contact with your body or clothing.
ALWAYS wear eye protection and rubber gloves, since the battery contains sulfuric acid which burns skin and eats through clothing.
CAUTION
Battery Safety
Wear safety glasses or face mask, protective clothes, and rubber gloves when working with battery.
ALWAYS check the battery terminals periodically to ensure that they are in good condition.
Use wire brush or sand paper to clean the battery terminals.
ALWAYS check battery for cracks or any other damage. If white pattern appears inside the battery or paste has accumulated at the bottom, replace the battery.
NEVER attempt to charge a battery that is frozen. The battery can explode unless first allowed to thaw.
If the pump will not be in operation for a long period of time, store in cool dry place and check the battery charge level every month to maintain the performance of the battery.
Check the battery regularly and make sure that each electrolyte level is to the bottom of the vent well (Figure 52). If necessary add only distilled water in a

Cleaning The Pump And Delivery System
DANGER
AMPUTATION HAZARD
D u r i n g r o u t i n e m a i n t e n a n c e o r removing material blockage, you will be required to put your hand in the concrete cylinders or near the
shuttle tube. You are at extreme risk of injury or AMPUATION if the engine is running or if pressure is in the hydraulic system.
Prior to performing any maintenance on the pump, follow described lock
Place a DO NOT OPERATE tag over the switch and disconnect the battery. The pressure reading on the accumulator pressure gauge MUST read zero. ALWAYS make sure the accumulator circuit pressure reads zero prior to performing any maintenance on the pump
